Download Species Interactions Review: Look at the food chain above. What do

Species Interactions Review:
1. Look at the food chain above. What do
the arrows represent?
2. The diagram to the right is a food web.
What is the source of energy that drives
this food web?
3. Which organisms are autotrophs?
4. Which organisms are herbivores?
5. Which organisms are carnivores?
6. Which organisms are decomposers?
7. The diagram below is an energy
pyramid. What types of organisms
would you find in level 4? In levels 3, 2
and 1?
8. Why is level 1 smaller than level 4?
9. What are the three types of data that could be used to create this type of
pyramid?
10. What ecological process is represented by the diagram below?
11. What are the two forms of
the process named in
question 9 and what is the difference between them?
12. The table to the right describes different types of species
relationships. Name each type of relationship. Hint: One
of the relationships is competition the other three are types
of symbiosis.
13. The graph to the left shows the population sizes of two
different species. What is the name for the type of interaction
illustrated in this graph?
14. What is the name for the role of an organism in the
ecosystem?
15. How do species interactions affect ecosystem stability?
Bio geochemical Cycles Review:
1.
Look at the diagram of the Nitrogen cycle to
the right. What organism (not illustrated) is
responsible for processes A, B, C, and D?
2. Name process A, process B, and process D
(Choices: denitrification, nitrogen fixation, and
decomposition).
3. True or False. Animals and Plants can get
useable nitrogen from the atmosphere.
4. Look at the cycle diagram of carbon dioxide and
oxygen below. What is the name of the process
that is represented by the arrow going from the
biosphere (picture of rabbit, plants and
decomposers) to the carbon dioxide in the atmosphere?
5. What is the name of the process that is represented by the arrow that goes from the carbon dioxide in the
atmosphere into the trees?
6. Where is the carbon stored before it undergoes combustion?
7. Plants play an important role in the
water cycle. They absorb water from the soil
and release it through their leaves. What is
the name of this process?
8. Which process(es) in the water cycle
help to clean the air?
9. Which process(es) in the water cycle
help to clean the water?
10. What is the source of energy that
drives the water cycle?
11.
What process releases nutrients stored
in animals and plants back into the soil after
the organisms have died?
12. True or False. Soil is made of both organic and inorganic material.
Humans and the Environment Review:
1. What type of growth has the human population experienced over the past 200 years?
2. What are some historical factors that have led to this rapid population growth?
3. CIRCLE the things that will INCREASE with increasing population growth and UNDERLINE the things that will
DECREASE with increasing population growth:
Habitat destruction
available clean water
Need for new technologies
pollution
food per person
4. What is the greenhouse effect?
5. Why is the ozone layer important?
deforestation
competition for resources
soil erosion
demand for agricultural land
6. What is the difference between renewable and non-renewable resources?
7. Look at the diagram of the causes and effects of air pollution. Name two gases that ONLY contribute to global
warming.
8. What are the sources of these two gases?
9. What two gases contribute to ozone destruction?
10. What are the sources of these two gases?
Population Review:
1.
2.
3.
4.
5.
6.
7.
Look at the diagram to the right. What type of
growth is observed from day 3 to day 7?
What type of population growth is observed when
looking at the whole graph?
What is the carrying capacity of this population?
Look at the second graph. What does the dashed line
represent?
How would you describe the population’s interaction with the
environment at time A? (equilibrium, chaos, exponential growth?)
What is a limiting factor?
CIRCLE the density INDEPENDENT factors. UNDERLINE the density
DEPENDENT factors:
competition
disease
weather
Natural disaster
predator/prey interactions
Habitat destruction
water shortage
parasites
crowding
